Gawo 1: CCEC Dizilo Engine Mafuta Malamulo

MAU OYAMBA

Bulletin ya Engineering iyi ndikulongosola kwanthawi zonse kwa kagwiritsidwe ntchito koyenera ndi kufunikira kokonza mafuta opaka injini ya Chongqing Cummins.Cholinga cha Engineering Bulletin iyi ndikusintha ndi kufewetsa kagwiritsidwe ntchito ka mafuta a Chongqing Cummins Engine Co., Ltd ( CCEC ) ndikusintha ndi kufewetsa malingaliro ndi malangizo kwa wogwiritsa ntchito kumapeto.

CCEC imafotokoza kugwiritsa ntchito mafuta apamwamba kwambiri, injini ya dizilo monga SAE15W/40.API CF - 4 kapena NT, KT ndi M 11 injini injector kapena SAE10W/30 , API CF-4 ya NT, KT ndi M11 injini yamakina injector yomwe imagwiritsidwa ntchito m'zigawo za altiplano za Qinghai ndi Xizang, API CH-4 ya QSK ndi M 11 electro-injector / electro-control injini, API C -4 mafuta angagwiritsidwe ntchito, koma nthawi yothira iyenera kuchepetsedwa mpaka maola 250.Zosefera zapamwamba kwambiri monga Fleetguard kapena zofananira .

CCEC imakhazikitsa malingaliro okhetsera mafuta pamagawo amafuta ndi kayendedwe kantchito.Kusunga nthawi yoyenera yosinthira mafuta ndi zosefera ndizofunikira kwambiri kuti injini isasungike.Onani buku lanu la Operation and Maintenance kuti mupeze malangizo atsatanetsatane okhudza nthawi yosinthira mafuta pa injini yanu.

Fyuluta imodzi yathunthu ndi fyuluta imodzi yodutsa imagwiritsidwa ntchito mwamphamvu pamainjini onse a CCEC (kupatulapo standby G-set ).Makasitomala samalola kutsitsa kusefera kulikonse kapena kulambalala fyuluta.

GAWO 1 : CCEC DIESEL ENGINE OIL ZOYENERA

CCEC imafotokoza kugwiritsa ntchito makina apamwamba kwambiri, msonkhano wamafuta a injini ya dizilo Amencan Petroleum Institute ( API) gulu la magwiridwe antchito a CF-4 kapena kupitilira apo ( QSK, M 11 electro-injection / electro-control engine yotchulidwa kugwiritsa ntchito CH-4, API CF-4 mafuta Itha kugwiritsidwa ntchito, koma nthawi yokhetsa iyenera kuchepetsedwa mpaka maola 250).Ngati injini iyenera kugwira ntchito popanda mafuta amtundu wa CF-4, mafuta amtundu wa CD amaloledwa (kupatula QSK, M 11 electro-injection / electro-control engine), koma kukhetsa kuyenera kufupikitsidwa ngati pakufunika.

Musagwiritse ntchito mafuta pansi pa CD kalasi uniformly.

Mafuta othyola mwapadera savomerezedwa kuti agwiritsidwe ntchito pamainjini atsopano kapena omangidwanso a CCEC.Ogulitsa mafuta ali ndi udindo pazabwino komanso magwiridwe antchito azinthu zawo.

1. Mafuta a Multigrade

CCEC Prescription ndi ntchito 15W40 multigrade ntchito yachibadwa pa kutentha yozungulira pamwamba -15C [5F].Kugwiritsiridwa ntchito kwa mafuta amitundu yambiri kumachepetsa mapangidwe a depositi, kumapangitsa kuti injini igwedezeke m'malo otentha kwambiri, ndikuwonjezera kulimba kwa injini posunga mafuta panthawi ya kutentha kwambiri.Popeza mafuta amitundu yosiyanasiyana awonetsedwa kuti amathandizira pafupifupi 30 peresenti yochepetsera mafuta, poyerekeza ndi mafuta a monograde, ndikofunikira kugwiritsa ntchito mafuta amitundu yosiyanasiyana kuti mutsimikizire kuti injini yanu ikwaniritsa zofunikira zotulutsa mpweya.Ngakhale kuti kalasi ya viscosity yomwe mumakonda ndi 15W-40, ma multigrades otsika a viscosity amatha kugwiritsidwa ntchito kumalo ozizira.Onani Chithunzi 1: Magiredi Opangidwa ndi SAE Oil Viscosity Grades at Ambient Temperatures.

Chithunzi 1: Zolemba SAE Mafuta Viscosity Grades vs Kutentha kozungulira

Mafuta akukumana ndi API CI - 4 ndi CJ - 4 ndi kalasi ya viscosity ya 10W30, ayenera kukumana ndi kutentha kochepa komanso kumeta ubweya wambiri wa 3.5 cSt., ndi zofunikira zovala mphete za Cummins Inc.ndi mayeso a Mack.Chifukwa chake, amatha kugwiritsidwa ntchito pakutentha kwakukulu kuposa mafuta a 10W30 omwe amakumana ndi magulu akale a API.Popeza mafutawa azikhala ndi mafilimu ocheperako kuposa mafuta a 15W40, zosefera zapamwamba za Fleetguard ziyenera kugwiritsidwa ntchito pamwamba pa 20C (70F).Ena ogulitsa mafuta atha kunena kuti mafuta amafuta awa ndi abwino.Cummins Inc. sangavomereze kapena kutsutsa chilichonse chomwe sichinapangidwe ndi Cummins Inc. Zonena izi zili pakati pa kasitomala ndi wogulitsa mafuta.Pezani kudzipereka kwa ogulitsa mafuta kuti mafuta apereka magwiridwe antchito bwino mu injini za Cummins, kapena musagwiritse ntchito mafutawo.

2. Mafuta a Monograde

Kugwiritsa ntchito mafuta a monograde kungakhudze kuwongolera mafuta a injini.Kufupikitsa kukhetsa kwamafuta kungafunike ndi mafuta a monograde, monga momwe kuwonetseredwa ndikuyang'anitsitsa momwe mafuta alili ndi zitsanzo zamafuta zomwe zakonzedwa.

CCEC imalimbikitsa kugwiritsa ntchito mafuta a monograde.

3. Kugwiritsa ntchito mafuta kwa CCEC ndi nthawi yovomerezeka yothirira onani Table 1.

Gulu 1:

Zindikirani:

1. .API CD&CF ilibe malire ku zinthu za sulfure, simplex CG-4&CH-4 mafuta amafuna zinthu za sulfure zosakwana 0.05 peresenti.Koma sulfure zili m'nyumba mafuta sangathe kukumana zosakwana 0,05 peresenti panopa.CCEC amalangiza H kapena ine kalasi mafuta akhoza kukwaniritsa zofunika zonse za CF-4/CH-4/CI-4, popanda malire okhutira sulfure.Chifukwa chake, CCEC imalimbikitsa H kapena I grade mafuta ku injini yotsika ya electro-injector.

2. CCEC Cummins jenereta wogulitsa amalimbikitsa 10W/30 CF-4 kapena pamwamba mafuta kuti injini ntchito pa tableland.Pamene malo ozungulira ali pamwamba -15 centigrade, lolani kugwiritsa ntchito 15w/40 cf-4, ch-4 mafuta mumkhalidwe woipa, koma muyenera kuwongolera kukhetsa kwapakati mkati mwa maola 150 kapena 250.Mafuta apadera a CCEC amalimbikitsidwa pamakina amagalimoto ndi omanga.

3. Mafuta a CH-4 amagwira ntchito ndi Fleetguard LF9009 fyuluta amatha kukulitsa nthawi yokhetsa mpaka maola 500.

4. Nthawi ya kukhetsayi imachokera ku Cummins yomwe ikulimbikitsidwa kukhetsa nthawi ndi injini yapanyumba yogwirira ntchito komanso mtundu wamafuta, osatsutsidwa ndi Cummins Inc.

5. Pamene bwino kalasi oi ntchito, wosuta ayenera mokwanira kuganizira kupirira kwa Zosefera, ndi kufupikitsa fyuluta kusintha imeneyi oyenera.Nthawi yosintha zosefera ndi maola 250 wamba.
